Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
For example, a battery with a maximum discharge current of 10 amps can provide twice as much power as a battery with a maximum discharge current of 5 amps. This number is important for two reasons. First, if you are using a device that requires more power than the battery can provide, then the battery will not be able to power the device and it ...

Disconnect the battery and try to resurrect the BMS by connecting a current limited 12-15V supply. When the battery will charge on the external power supply, get yourself a VE.Bus dongle and program the Multiplus for LiFePo batteries. Reconnect system and try again.
The service life of a deep cycle battery is measured in discharge cycles. This is usally promised by the manufacturer of the battery. Each 100ah promised by your battery bank is at a 20 hourly rate at 5 amps. The amp-hours drops the greater the current draw. At 5 hours on a 100 a-h battery for example you might get 82a-h at 16 amps.

Let''s explore a few commonly observed discharge profiles: 4.1 Constant Current (CC) Discharge. During the initial phase of a lithium-ion battery''s discharge, it often follows a constant current (CC) profile.

C-Rate of discharge is a measure of the rate at which the battery is being discharged when compared to its rated capacity. A C/2 or 0.5C rate means that this particular discharge current will discharge the battery in 2 hours. For example, a 50Ah battery will discharge at 25A for 2 hours. A similar analogy applies to the C-rate of charge.

It represents the discharge rate relative to the battery''s maximum capacity. For example, a battery with a 1C rating can provide a current equal to its capacity for one hour. The C rating helps determine the maximum safe continuous discharge rate and the duration the battery can handle that discharge.
However, extended exposure to elevated temperatures leads to rapid aging and diminishes battery life. Current Discharge Rate. The rate at which a battery is discharged can also affect its characteristics. When you discharge a battery at a high rate (i.e., a large current is drawn quickly), its effective capacity can decrease.
When the discharge pulse current ends, the voltage will slowly rise from point D to point E; When the charging pulse current ends, the voltage slowly drops from H to I. After the discharge pulse and charge pulse end, the battery voltage will still change slowly due to battery''s polarization effect.
Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real available capacity will be smaller (it may be much smaller). Discharging the battery with a lower current will extend the real available capacity a little bit.
Performing a controlled battery discharge test requires the use of a battery discharge tester. The steps to perform a controlled battery discharge test are as follows: Connect the battery to the discharge tester. Set the discharge rate and time. Start the discharge test. Monitor the battery voltage during the discharge test.
Discharge is rated in "C" for example if your selected battery states 20C the maximum discharge is 20 * Battery capacity. One of the reasons LiPo batteries are used in RC projects is the fact they can normally handle a high C rate (They can deliver a punch to the high-power motors). If we look at the two options, you provided

The charging/discharge rate may be ...
LiFePO4 cells have a nominal voltage of 3.2V, much higher than the 2V for lead acid batteries. This higher stack voltage means less relative change as the battery discharges. For example, a 12V LiFePO4 battery may go from 14.4V fully charged to 12.8V near empty, a change of 12%. A 12V lead acid battery goes from 12.6V to 10.5V, a change of 20%.
